You mentioned that Heathkit used 6146's in virtually all of their
gear. That is a valid statement, but they used 6GE5 sweep tubes in
the lower price-point HW-series monobanders, including the ones for
MARS/CAP. It was a purely a matter of economics, I think. Retail
price aside, there had to have been more manufacturing volume on the
sweep tubes, because just about every family had a TV set.

I now have a 4B-line, and also a bunch of HW-series rigs. The 6GE5's
are fairly inexpensive even today, compared to 6146A's or W's or the
later GE 6146B's that Heathikit blessed.

Yup... for sure... I forgot about those monobanders. I even had one
myself---the HW-32A.

Well, you raise the question that's been on my mind for quite awhile---just
what was the production on the 6146? I don't have the slightest idea how to
find that tidbit. They were well in production before TV became
commonplace---maybe 10 years or so. Just what was the production figure on
the 6JB6? To be honest the 6JB6 doesn't sound like a common tube. I recall
the horizontal deflection amplifier tubes like the 6DQ5 and 6DQ6 but looking
in my 1961 RCA tube handbook I don't seen the 6JB6 listed.

I recall, Kenwood had 6146's in their TS-520, correct me if I'm wrong but
wasn't it a 6146 of Japanese production ( I remember they had the shiny
chrome finish on the metal surfaces that typified some of the Japanese
parts)?
